It's logical that Kerry would want to attack Bush's strength. The American people trust Bush more than the do Kerry when polled on the War On Terror. Kerry and his cronies are playing this out as some VRWC hatched to bring him down, when it was Sandy Berger doing this on his own time since October of 2003, while working in the Kerry campaign as a former Clinton cronie.

Not really logical at all. Kerry would be vastly better off to attack Bush as a wimp, declare that the Army needs to triple in size, and say that he would invade any country found to be helping the enemies of America. He should praise what Bush has done, but say it has not been enough.
This would then position Kerry to benefit from any terrorist attacks on American soil before the balloting, and neuter the Bush strong on defense advantage.
In fact, he can harp on how gosh awful the economy in Bloodsuckeddrybyunionsville, USA, and then repeat the message at Doneinbyhightaxesburg USA, stating that the closed Army based needs to be reopened for business. Kerry could go to every closed military base and proclaim loudly about how we need it back in operation to get the muscle up to wipe out terrorists wherever they may be found.
But, it would have a crediblity problem for Kerry since he never found a weapons system worthy of his support.
